EBC 5-Button Floating Stainless 11.8" Front Rotor for Harley

Product Description

EBC 11.8" Floating Front Brake Rotor for Harley-Davidson

Upgrade the front braking performance of your Harley-Davidson with the EBC MD530 Floating Front Brake Rotor. Designed for compatible Harley-Davidson models using a 300mm front brake disc, the MD530 combines a heat-treated stainless steel braking surface with a polished center carrier and full-floating construction for consistent braking performance and a clean custom appearance.

The floating design allows the outer braking ring to move independently of the center carrier as brake temperatures change. This controlled movement helps compensate for thermal expansion, maintain consistent brake pad alignment and reduce stress on the rotor during repeated braking and heat cycles.

EBC uses a five-button floating configuration on the MD530 to reduce rotating mass while maintaining the benefits of a fully floating rotor. EBC specifically positions its five-button Harley-Davidson rotors for motorcycles equipped with twin front brake discs.

The rotor measures 11.8" / 300mm in diameter with a 5mm-thick braking surface and 56.4mm center bore. Counterbored mounting holes provide compatibility with the appropriate Harley-Davidson wheel hubs, making the MD530 a premium replacement for a wide range of later Dyna, Softail, Touring, Trike and Sportster applications.

Important: EBC identifies the five-button floating design as intended primarily for motorcycles equipped with twin front brake rotors.

Note: Harley-Davidson used multiple front wheel hubs, rotor diameters and caliper configurations across these applications. Verify your motorcycle's rotor diameter, 56.4mm center bore, bolt pattern and brake configuration before ordering. Dual-disc applications require one rotor per side.
